Hello,
I am trying to simulate the excitation of a laser pulse on the surface of a slab. I have performed my thermal transient analysis in workbench and I want to couple the results with LS-dyna (The reason that I am using LS-Dyna is because I want to use the non reflecting boundaries that only LS-dyna offers in order to avoid the elastic wave reflections therefore reducing the simulation domain). I am using ANSYS 2024 R1 but It seems I cannot import the heat flux results to LS-Dyna Workbench in order to perform the structural part there. Has anyone else performed something similar?
thank you for all your help and support

Hi Emmanouil, 

Currently, within LS-DYNA WB we do not offer native support to import the heat flux other than temperature using the following workflow

However, you can explore the *BOUNDARY_FLUX_SET to set the flux values as load curves in the LCID for every segment inferred by the element or perform the entire thermal step within LSDYNA WB and use dynain or multi-step analysis workflow to proceed with the next steps.

Cheers, Ram

Thank you for your answer! Although it seems that in ANSYS2024 R1 does not let me link the solution of the thermal simulation ti LS-Dyna

thank you for all your help
